The correct answer to the problem AS WRITTEN is $56. Whether there are two or two hundred million students it still costs $56 for each student, which is what the your wording asks for. Often math problems are written by someone with an intuitive proficiency for math – they know the answer and how to get it – and so the words come long after. Had you written: If there were 20 million high school students in the U.S., approximately how much would it cost to provide this service to all of them for one year? – your wording would have been a more accurate description of of the problem and it’s answer. “each” refers to individuals in a group, “all” refers to the whole group
